Be careful with xhost.  Xwindows tends to have lots of security issues (http://www.securityportal.com/list-archive/bugtraq/).  Setting "xhost +" will allow *anybody* to make a connection to your box on port 6000.  It is much better to specify the specific hosts that you wish to allow to connect by entering xhost [IP address of hostname].  For example, "xhost 192.168.0.5".

I don't know where to change this permanently, but if you type
'xhost +' before you su it will give everyone permission to use your display.
